MySQL Error 1645: RESIGNAL Without Active Handler
Description
This error occurs in MySQL stored procedures or functions when the `RESIGNAL` statement is executed, but no active condition handler is currently processing an error. It indicates an attempt to re-raise an error outside the expected context of an `UNDO`, `CONTINUE`, or `EXIT` handler.

Known Causes
3 known causesRESIGNAL Outside Handler

The `RESIGNAL` statement was executed after the declared error handler had already finished processing the original error and exited its scope.
Incorrect Logic Flow
The logic within the stored routine or handler caused `RESIGNAL` to be reached when no error was being actively handled, leading to an invalid context.
